Oxidative synthesis of higher hydrocarbons from CO2 and CH4 by streamer discharges

An experimental investigation on oxidative synthesis of ethane and ethylene from CH4 using CO2 as an oxidant has been performed by streamer discharge reactions, which are initiated by an AC electric field. This gas discharge promotes the methane conversion to reach a high yield of C-2 hydrocarbons of 20% similar to 45% with a methane conversion of 25% similar to 80% and a conversion of carbon dioxide of 8% similar to 40%. The reactions for these conversions are: 2CH(4) + CO2 --> C2H6 + CO + H2O and 2CH(4) + 2CO(2) --> C2H4 + 2CO + 2 H2O. A possible pathway of Cr formation was also present in this letter.
